Fortunately for @arcange, all the data can be replayed, but it is a very time consuming process if he has to start again at block 0 so it is just a huge hassle.
If it's only the database he lost, then yes, it's only time and hassle to get it back to date. He mentions another backup off site, so maybe he doesn't have to start from block 0.
I am curious how they got elevated permissions though, HiveSQL is read only for users.
Yeah, that's something he (or the investigators) needs to figure out, or this can happen again.
